Application October 31, 1949;-Serial No. 124527 11 1 Claims. 1

This invention relates .toadvertising devices and more particularly to a display sign adapted to display continuous or progressive :a'dvertising matter.

An object of this invention is to provide an advertising device which is especially attractive and well adapted to hold an observers interest.

A further object of the invention is to provide an automatic continuous'or progressive display device using novel means for activating a strip of film placed therein.

Another object of the invention resides in the provision of concentric guide means for housing a film strip of larger size and design so that the film may be conveniently and easily fed before a transparent screen so as to novelly display an advertisers wares.

A yet further object of the invention is toisolate the drive means of the inventionfrom the film whereby the film is protected to a greater degree from deterioration dueto grease or other oils.

Still further objects of the invention reside in the provision of a display sign that is strong, durable, highly efiicient in operation, simple in construction and manufacturer, easy-t operate,

vention in greatest detail;

.Figure 3 is a horizontal sectional view as taken along line 3-3 in Figure 1 and showing the guide .means comprising another element of the invention its operative position;

Figure l is a vertical, sectional view as taken along line Al4 in Figure 2;

Figure 5 is another verticalsectional View this time taken along line 5-5 in-Figure 1;

Figure 6 is a sectional detail showing how the film is entrained about the film engaging means of the display sign; and,

Figure 7 is an elevational detail showing how the roller bearings are journaled in the guide means of the present invention.

generally indicated by reference numeral 12 which includes several elements which maybe bolted, screwed-together, welded, or elsewise-secured in any convenient and desirable fashion. These-elements include a backplate I-4,;a ,top plate l5,-a baseplate'ld'to which issecured in any convenient manner,;-such as by screws flfl, a

container 22 i for the operative drivingmeapspf the invention. The container 22 also consists-of a back plate 24, a bottom 26 and a frontplate 28. Additionally, side plates ;30 and ;3-2 are: provided for the containerZZ. Angleirons 34 are :usedto reinforce the structure in a convenientmanner.

A pair .of arcuatesidepieces 35 and 38- which are secured to the topplatei l6, bottomplatevm, and back plate it are provided. -As show-nibest iii-Figure 7, one, end of the plates 3 6'and'38 are provided with rollerbearings 40 which -areijournaled within recesses 42 formed in the QlllClSyQf the'plates. The. other endsof the plates'36' nd 38 are secured to a frame member 4'4, .=WhiQh.-..i

also conveniently and removablyiattached; to the top member l6 andthe bottom or base member 88. transparent plate of glass or; plastic material and designatedzby reference numeral .416 is fitted into the frame which may be formedof any suitable decorative molding. Securedtothe bottom strip of the frame molding 44 is a trayg la in which a fluorescent tube '50 is operatively secured so as to provide means, for illuminating the interior of the casing l2.

Journaled within the top and bottom of the casing l2 are a pair ofjspaced shafts suchas the one indicated by reference-numera152; Each of the shafts have their lower end '54 extending --without the bottom of the'casing and into the chamber 22. The sprocket wheel 56 is securedto the end of the shaft 52 and a chain 58 is trained thereabout'to transfer from sprocket wheel "60 driven by prime mover v'62 which may be an-relectrio motor or other similar .device. A suitable reductiongear. is used to reduce the speed of the motor 62 to the degree: necessary for desirable actuation of the shafts '52.

An additional pair of spaced sprockets 64 and 66 are secured to the shaft 52 by any suitable means adjacent the top and bottom thereof. 00- axial with the shafts 52 are a plurality of spaced arcuate guides such as those indicated by reference numerals 68, 10, 14, 16, and 18. on each of the Vertically extending ends of these guides are secured roller bearings similar to the roller bearing 40 secured to the plate 38 which is best shown in Figure 7 in order to reduce friction on the film.

The film or elongated strip of paper or cloth Ihaving advertising matter there printed upon pass between guide 68 and plate v38 a-n'd thence to the other side of the sign. The strip 89 is pref- :erably endless in construction and is strong enough to be continuously clearly viewed advertising medium.

rotated to provide a It is contemplated to trim the sign with colored neon lights as desired. Additional decorative moldings about the frame or casing may be easily applied. Additionally, the back wall l4 will be provided with a small trap door at the bottom for easy access and adjustment of the device.

Since this device is easily adapted to be used about corners, upright, or in any convenient man ner, it may be easily used on subway trains, buses, and practically any other convenient place.

Since from the foregoing, the construction and advantages of this display sign are readily apparent, further description is believed to be unnecessary,

tially concentric guide means substantially concentric with said film engaging means secured to said casing, and drive means operatively connected to said film engaging means, said film engaging means comprising a shaft journaled in said casing, one end of said shaft extending with out said casing, spaced sprockets secured to said shaft within said casing and adapted to receive a film trained therearound, and a sprocket wheel secured to said end of said shaft, and said drive means engaging said sprocket wheel.

2. A reeling system installed in a casing comprising film engaging means journaled in said casing, a plurality of radially spaced substantially concentric guide means substantially concentric with said film engaging means secured to said casing, and drive means operatively connected to said film engaging means, said film engaging means comprising a shaft journaled in said casing, one end of said shaft extending without said casing, spaced sprockets secured to said shaft within said casing and adapted to receive a film trained therearound, and a sprocket wheel secured to said end of said shaft, and a chain trained about said sprocket wheel and operatively connected to a prime mover.

3. The structure of claim 2 wherein said guide means comprise a series of substantially concentric arcuate plates substantially co-axial with said film engaging means.

4. The structure of claim 3 including roller bearings secured to the vertical ends of said plates.

5. A reeling system installed in a casing comprising a pair of spaced shafts journaled in said casing, a plurality of substantially concentric plates secured to said casing substantially coaxial with said shafts, said plates being radially spaced, and drive means operatively connected to said shafts.

6. The structure of claim 5 including spaced sprockets secured to each of said shafts Within said casing and adapted to receive a film trained therearound.

7. The structure of claim 6 wherein said shafts each have an end extending without said casing, sprocket wheels secured to said ends of said shafts, said drive means engaging said sprocket wheels,

8. The structure of claim 7 wherein said drive means comprise a chain trained about said sprocket wheel and operatively connected to a prime mover.

9. The structure of claim 8 wherein said guide means comprise a series of substantially concentric arcuate plates substantially co-axial with said film engaging means.

10. The structure of claim 9 including roller bearings secured to the vertical ends of said plates.
